What is PETG?

PETG, or polyethylene terephthalate glycol-modified, is a versatile thermoplastic used in various commercial and industrial applications. It has high impact resistance, clarity, and strength, making it an ideal choice for products that need to be durable and attractive. Some of the most common uses for PETG include food packaging, eyeglass frames, medical devices, and 3D printing filaments. This material is also widely used in prototyping, and it has a variety of properties that make it ideal for this purpose.

What's the Difference between PET and PETG?

PET is a thermoplastic polymer resin of the polyester family used in beverage, food and other liquid containers. PETG is a variation of PET that has enhanced mechanical properties making it an ideal material for 3D printing. Both are made from thermoplastics, meaning they can be melted and reshaped repeatedly, but there are a few key distinctions between them.

  • PET is comparatively brittle and less impact-resistant than PETG, so it might not be the best choice for objects that will be subjected to a lot of wear and tear.
  • PET is also more susceptible to UV light damage, while PETG is far more durable in both regards.
  • PET is a clear, strong plastic that's often used for bottles. PETG is also clear, but it's slightly softer than PET and has a slightly higher melting point. It's a popular choice for 3D printing filaments because it prints easily and doesn't warp.

Advantages of PETG


If you're looking for a filament that combines strength and impact resistance, PETG is the perfect solution. This material prints easily and produces objects with a high degree of detail. What's more, PETG is ideal for making products that need to withstand tough conditions. So if you're looking for a filament that can handle anything, PETG is the way to go.

Food-Safe and Recyclable

Have you ever wondered if the types of plastics you're using are safe for food contact? Polyethylene terephthalate glycol-modified, or PETG, is a type of plastic that is specifically designed for food contact. In fact, it's even recyclable. If you're looking for a safe and sustainable option for your next kitchen project, PETG might be a perfect choice.

Easily Formable

PETG is a great material for various applications because it is both vacuum and thermoformable. This means it can be vacuum formed or thermoformed into many different shapes without losing its properties. This makes PETG a versatile option for parts and components in various industries. Additionally, PETG is non-toxic and environmentally friendly, making it a good choice for medical and food applications.

Because the material is see-through, it can be combined with other colors to create stunning displays. In addition, PETG is durable and resilient, making it a great choice for various applications. If you're looking for an eye-catching material that's both strong and stunning, PETG is a perfect choice.

Non-Toxic and Odorless Emissions

Are you looking for a filament that is non-toxic and odorless? Look no further than PETG. This versatile material is perfect for 3D printing, and it produces high-quality results. Best of all, PETG doesn't release any harmful fumes, so you can rest easy knowing that your prints will be safe to use. Plus, the lack of odor makes this filament ideal for classrooms or busy offices.

Disadvantages of PETG

Correct Temperature Parameters Need To Be Followed

3D printing enthusiasts often experiment with different filaments to see what prints they can create. Some filaments are more difficult to work with than others, and PETG requires special temperature parameters to achieve the best results. If you have ever tried to print with PETG filament, the results weren't what you were hoping for, and your prints came out too brittle or with a decreased lifespan compared to ABS prints. If so, it's likely that you weren't using the correct temperature parameters for printing with PETG.

PETG is Prone to Oozing

When it comes to 3D printing filaments, there are a few main options: PLA, ABS, and PETG. Of these, PETG is the most recent addition, and it's quickly becoming a favorite among 3D printing enthusiasts. One of the benefits of PETG is that it doesn't warp or crack as easily as PLA or ABS. However, one downside is that PETG tends to ooze more than other filaments.

Negative Environmental Impact

It is important to be mindful of the potential environmental impact of any product when considering its purchase. In the case of PETG, there is a possibility that it can have a negative effect on the environment if not disposed of properly. Therefore, it is important to take care in both the disposal and recycling of PETG products. By being aware of these issues, we can help minimize any potential harm to our environment.

Absorbs Water

If you store your PETG filament in a humid environment, it will absorb water and become useless. To prevent this from happening, make sure to store your filament in a dry place. You can also use desiccant packets to help soak up any extra moisture in the air. By following these tips, you'll be able to use your PETG filament for many prints to come.

PETG Applications
